Description

CROSS-REFERENCE TO RELATED APPLICATION

This patent application claims priority to U.S. Provisional Patent Application No. 62/945,541, filed on Dec. 9, 2019, entitled “DYNAMIC USER EQUIPMENT PARAMETER ADAPTATION STATUS REPORT,” and assigned to the assignee hereof. The disclosure of the prior application is considered part of and is incorporated by reference into this patent application.

FIELD OF THE DISCLOSURE

Aspects of the present disclosure generally relate to wireless communication and to techniques and apparatuses for a dynamic user equipment parameter adaptation status report.

BACKGROUND

Wireless communication systems are widely deployed to provide various telecommunication services such as telephony, video, data, messaging, and broadcasts. Typical wireless communication systems may employ multiple-access technologies capable of supporting communication with multiple users by sharing available system resources (e.g., bandwidth, transmit power, and/or the like). Examples of such multiple-access technologies include code division multiple access (CDMA) systems, time division multiple access (TDMA) systems, frequency-division multiple access (FDMA) systems, orthogonal frequency-division multiple access (OFDMA) systems, single-carrier frequency-division multiple access (SC-FDMA) systems, time division synchronous code division multiple access (TD-SCDMA) systems, and Long Term Evolution (LTE). LTE/LTE-Advanced is a set of enhancements to the Universal Mobile Telecommunications System (UMTS) mobile standard promulgated by the Third Generation Partnership Project (3GPP).

A wireless communication network may include a number of base stations (BSs) that can support communication for a number of user equipment (UEs). A user equipment (UE) may communicate with a base station (BS) via the downlink and uplink. The downlink (or forward link) refers to the communication link from the BS to the UE, and the uplink (or reverse link) refers to the communication link from the UE to the BS. As will be described in more detail herein, a BS may be referred to as a Node B, a gNB, an access point (AP), a radio head, a transmit receive point (TRP), a New Radio (NR) BS, a 5G Node B, and/or the like.

The above multiple access technologies have been adopted in various telecommunication standards to provide a common protocol that enables different user equipment to communicate on a municipal, national, regional, and even global level. New Radio (NR), which may also be referred to as 5G, is a set of enhancements to the LTE mobile standard promulgated by the Third Generation Partnership Project (3GPP). NR is designed to better support mobile broadband Internet access by improving spectral efficiency, lowering costs, improving services, making use of new spectrum, and better integrating with other open standards using orthogonal frequency division multiplexing (OFDM) with a cyclic prefix (CP) (CP-OFDM) on the downlink (DL), using CP-OFDM and/or SC-FDM (e.g., also known as discrete Fourier transform spread OFDM (DFT-s-OFDM)) on the uplink (UL), as well as supporting beamforming, multiple-input multiple-output (MIMO) antenna technology, and carrier aggregation. However, as the demand for mobile broadband access continues to increase, there exists a need for further improvements in LTE and NR technologies. Preferably, these improvements should be applicable to other multiple access technologies and the telecommunication standards that employ these technologies.

DETAILED DESCRIPTION

Various aspects of the disclosure are described more fully hereinafter with reference to the accompanying drawings. This disclosure may, however, be embodied in many different forms and should not be construed as limited to any specific structure or function presented throughout this disclosure. Rather, these aspects are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the disclosure to those skilled in the art. Based on the teachings herein one skilled in the art should appreciate that the scope of the disclosure is intended to cover any aspect of the disclosure disclosed herein, whether implemented independently of or combined with any other aspect of the disclosure. For example, an apparatus may be implemented or a method may be practiced using any number of the aspects set forth herein.

It should be understood that any aspect of the disclosure disclosed herein may be embodied by one or more elements of a claim.

Several aspects of telecommunication systems will now be presented with reference to various apparatuses and techniques. These apparatuses and techniques will be described in the following detailed description and illustrated in the accompanying drawings by various blocks, modules, components, circuits, steps, processes, algorithms, and/or the like (collectively referred to as “elements”). These elements may be implemented using hardware, software, or combinations thereof. Whether such elements are implemented as hardware or software depends upon the particular application and design constraints imposed on the overall system.

It should be noted that while aspects may be described herein using terminology commonly associated with 3G and/or 4G wireless technologies, aspects of the present disclosure can be applied in other generation-based communication systems, such as 5G and later, including NR technologies.

FIG. 1 is a diagram illustrating a wireless network 100 in which aspects of the present disclosure may be practiced. The wireless network 100 may be an LTE network or some other wireless network, such as a 5G or NR network. The wireless network 100 may include a number of BSs 110 (shown as BS 110 a, BS 110 b, BS 110 c, and BS 110 d) and other network entities. ABS is an entity that communicates with user equipment (UE) and may also be referred to as a base station, a NR BS, a Node B, a gNB, a 5G node B (NB), an access point, a transmit receive point (TRP), and/or the like. Each BS may provide communication coverage for a particular geographic area. In 3GPP, the term “cell” can refer to a coverage area of a BS and/or a BS subsystem serving this coverage area, depending on the context in which the term is used.

A BS may provide communication coverage for a macro cell, a pico cell, a femto cell, and/or another type of cell. A macro cell may cover a relatively large geographic area (e.g., several kilometers in radius) and may allow unrestricted access by UEs with service subscription. A pico cell may cover a relatively small geographic area and may allow unrestricted access by UEs with service subscription. A femto cell may cover a relatively small geographic area (e.g., a home) and may allow restricted access by UEs having association with the femto cell (e.g., UEs in a closed subscriber group (CSG)). ABS for a macro cell may be referred to as a macro BS. ABS for a pico cell may be referred to as a pico BS. A BS for a femto cell may be referred to as a femto BS or a home BS. In the example shown in FIG. 1 , a BS 110 a may be a macro BS for a macro cell 102 a, a BS 110 b may be a pico BS for a pico cell 102 b, and a BS 110 c may be a femto BS for a femto cell 102 c. A BS may support one or multiple (e.g., three) cells. The terms “eNB”, “base station”, “NR BS”, “gNB”, “TRP”, “AP”, “node B”, “5G NB”, and “cell” may be used interchangeably herein.

In some aspects, a cell may not necessarily be stationary, and the geographic area of the cell may move according to the location of a mobile BS. In some aspects, the BSs may be interconnected to one another and/or to one or more other BSs or network nodes (not shown) in the wireless network 100 through various types of backhaul interfaces such as a direct physical connection, a virtual network, and/or the like using any suitable transport network.

Wireless network

100 may also include relay stations. A relay station is an entity that can receive a transmission of data from an upstream station (e.g., a BS or a UE) and send a transmission of the data to a downstream station (e.g., a UE or a BS). A relay station may also be a UE that can relay transmissions for other UEs. In the example shown in FIG. 1 , a relay station 110 d may communicate with macro BS 110 a and a UE 120 d in order to facilitate communication between BS 110 a and UE 120 d. A relay station may also be referred to as a relay BS, a relay base station, a relay, and/or the like.

Wireless network

100 may be a heterogeneous network that includes BSs of different types, e.g., macro BSs, pico BSs, femto BSs, relay BSs, and/or the like. These different types of BSs may have different transmit power levels, different coverage areas, and different impacts on interference in wireless network 100. For example, macro BSs may have a high transmit power level (e.g., 5 to 40 Watts) whereas pico BSs, femto BSs, and relay BSs may have lower transmit power levels (e.g., 0.1 to 2 Watts).

A network controller 130 may couple to a set of BSs and may provide coordination and control for these BSs. Network controller 130 may communicate with the BSs via a backhaul. The BSs may also communicate with one another, e.g., directly or indirectly via a wireless or wireline backhaul.

UEs 120 (e.g., 120 a, 120 b, 120 c) may be dispersed throughout wireless network 100, and each UE may be stationary or mobile. A UE may also be referred to as an access terminal, a terminal, a mobile station, a subscriber unit, a station, and/or the like. A UE may be a cellular phone (e.g., a smart phone), a personal digital assistant (PDA), a wireless modem, a wireless communication device, a handheld device, a laptop computer, a cordless phone, a wireless local loop (WLL) station, a tablet, a camera, a gaming device, a netbook, a smartbook, an ultrabook, a medical device or equipment, biometric sensors/devices, wearable devices (smart watches, smart clothing, smart glasses, smart wrist bands, smart jewelry (e.g., smart ring, smart bracelet)), an entertainment device (e.g., a music or video device, or a satellite radio), a vehicular component or sensor, smart meters/sensors, industrial manufacturing equipment, a global positioning system device, or any other suitable device that is configured to communicate via a wireless or wired medium.

Some UEs may be considered machine-type communication (MTC) or evolved or enhanced machine-type communication (eMTC) UEs. MTC and eMTC UEs include, for example, robots, drones, remote devices, sensors, meters, monitors, location tags, and/or the like, that may communicate with a base station, another device (e.g., remote device), or some other entity. A wireless node may provide, for example, connectivity for or to a network (e.g., a wide area network such as Internet or a cellular network) via a wired or wireless communication link. Some UEs may be considered Internet-of-Things (IoT) devices, and/or may be implemented as NB-IoT (narrowband internet of things) devices. Some UEs may be considered a Customer Premises Equipment (CPE). UE 120 may be included inside a housing that houses components of UE 120, such as processor components, memory components, and/or the like.

In general, any number of wireless networks may be deployed in a given geographic area. Each wireless network may support a particular radio access technology (RAT) and may operate on one or more frequencies. A RAT may also be referred to as a radio technology, an air interface, and/or the like. A frequency may also be referred to as a carrier, a frequency channel, and/or the like. Each frequency may support a single RAT in a given geographic area in order to avoid interference between wireless networks of different RATs. In some cases, NR or 5G RAT networks may be deployed.

In some aspects, two or more UEs 120 (e.g., shown as UE 120 a and UE 120 e) may communicate directly using one or more sidelink channels (e.g., without using a base station 110 as an intermediary to communicate with one another). For example, the UEs 120 may communicate using peer-to-peer (P2P) communications, device-to-device (D2D) communications, a vehicle-to-everything (V2X) protocol (e.g., which may include a vehicle-to-vehicle (V2V) protocol, a vehicle-to-infrastructure (V2I) protocol, and/or the like), a mesh network, and/or the like. In this case, the UE 120 may perform scheduling operations, resource selection operations, and/or other operations described elsewhere herein as being performed by the base station 110.

As indicated above, FIG. 1 is provided as an example. Other examples may differ from what is described with regard to FIG. 1 .

FIG. 2 shows a block diagram of a design 200 of base station 110 and UE 120, which may be one of the base stations and one of the UEs in FIG. 1 . Base station 110 may be equipped with T antennas 234 a through 234 t, and UE 120 may be equipped with R antennas 252 a through 252 r, where in general T≥1 and R≥1.

At base station 110, a transmit processor 220 may receive data from a data source 212 for one or more UEs, select one or more modulation and coding schemes (MCS) for each UE based at least in part on channel quality indicators (CQIs) received from the UE, process (e.g., encode and modulate) the data for each UE based at least in part on the MCS(s) selected for the UE, and provide data symbols for all UEs. Transmit processor 220 may also process system information (e.g., for semi-static resource partitioning information (SRPI) and/or the like) and control information (e.g., CQI requests, grants, upper layer signaling, and/or the like) and provide overhead symbols and control symbols. Transmit processor 220 may also generate reference symbols for reference signals (e.g., the cell-specific reference signal (CRS)) and synchronization signals (e.g., the primary synchronization signal (PSS) and secondary synchronization signal (SSS)). A transmit (TX) multiple-input multiple-output (MIMO) processor 230 may perform spatial processing (e.g., precoding) on the data symbols, the control symbols, the overhead symbols, and/or the reference symbols, if applicable, and may provide T output symbol streams to T modulators (MODs) 232 a through 232 t. Each modulator 232 may process a respective output symbol stream (e.g., for OFDM and/or the like) to obtain an output sample stream. Each modulator 232 may further process (e.g., convert to analog, amplify, filter, and upconvert) the output sample stream to obtain a downlink signal. T downlink signals from modulators 232 a through 232 t may be transmitted via T antennas 234 a through 234 t, respectively. According to various aspects described in more detail below, the synchronization signals can be generated with location encoding to convey additional information.

At UE 120, antennas 252 a through 252 r may receive the downlink signals from base station 110 and/or other base stations and may provide received signals to demodulators (DEMODs) 254 a through 254 r, respectively. Each demodulator 254 may condition (e.g., filter, amplify, downconvert, and digitize) a received signal to obtain input samples. Each demodulator 254 may further process the input samples (e.g., for OFDM and/or the like) to obtain received symbols. A MIMO detector 256 may obtain received symbols from all R demodulators 254 a through 254 r, perform MIMO detection on the received symbols if applicable, and provide detected symbols. A receive processor 258 may process (e.g., demodulate and decode) the detected symbols, provide decoded data for UE 120 to a data sink 260, and provide decoded control information and system information to a controller/processor 280. A channel processor may determine reference signal received power (RSRP), received signal strength indicator (RSSI), reference signal received quality (RSRQ), channel quality indicator (CQI), and/or the like. In some aspects, one or more components of UE 120 may be included in a housing.

On the uplink, at UE 120, a transmit processor 264 may receive and process data from a data source 262 and control information (e.g., for reports comprising RSRP, RSSI, RSRQ, CQI, and/or the like) from controller/processor 280. Transmit processor 264 may also generate reference symbols for one or more reference signals. The symbols from transmit processor 264 may be precoded by a TX MIMO processor 266 if applicable, further processed by modulators 254 a through 254 r (e.g., for DFT-s-OFDM, CP-OFDM, and/or the like), and transmitted to base station 110. At base station 110, the uplink signals from UE 120 and other UEs may be received by antennas 234, processed by demodulators 232, detected by a MIMO detector 236 if applicable, and further processed by a receive processor 238 to obtain decoded data and control information sent by UE 120. Receive processor 238 may provide the decoded data to a data sink 239 and the decoded control information to controller/processor 240. Base station 110 may include communication unit 244 and communicate to network controller 130 via communication unit 244. Network controller 130 may include communication unit 294, controller/processor 290, and memory 292.

Controller/processor 240 of base station 110, controller/processor 280 of UE 120, and/or any other component(s) of FIG. 2 may perform one or more techniques associated with a dynamic UE parameter adaptation status report, as described in more detail elsewhere herein. For example, controller/processor 240 of base station 110, controller/processor 280 of UE 120, and/or any other component(s) of FIG. 2 may perform or direct operations of, for example, process 400 of FIG. 4 , process 500 of FIG. 5 , and/or other processes as described herein.

Memories

242 and 282 may store data and program codes for base station 110 and UE 120, respectively. In some aspects, memory 242 and/or memory 282 may comprise a non-transitory computer-readable medium storing one or more instructions for wireless communication. For example, the one or more instructions, when executed by one or more processors of the base station 110 and/or the UE 120, may perform or direct operations of, for example, process 400 of FIG. 4 , process 500 of FIG. 5 , and/or other processes as described herein. A scheduler 246 may schedule UEs for data transmission on the downlink and/or uplink.

In some aspects, UE 120 may include means for receiving an indication to transmit a dynamic UE parameter adaptation report to a BS 110, means for transmitting the dynamic UE parameter adaptation report to the BS 110 based at least in part on receiving the indication, and/or the like. In some aspects, such means may include one or more components of UE 120 described in connection with FIG. 2 , such as controller/processor 280, transmit processor 264, TX MIMO processor 266, MOD 254, antenna 252, DEMOD 254, MIMO detector 256, receive processor 258, and/or the like.

In some aspects, base station 110 may include means for transmitting, to a UE 120, an indication to transmit a dynamic UE parameter adaptation report, means for receiving, from the UE 120, the dynamic UE parameter adaptation report based at least in part on transmitting the indication, and/or the like. In some aspects, such means may include one or more components of base station 110 described in connection with FIG. 2 , such as antenna 234, DEMOD 232, MIMO detector 236, receive processor 238, controller/processor 240, transmit processor 220, TX MIMO processor 230, MOD 232, antenna 234, and/or the like.

As indicated above, FIG. 2 is provided as an example. Other examples may differ from what is described with regard to FIG. 2 .

Dynamic UE parameter adaption is a technique that can be used to dynamically configure various UE parameters for power saving at a UE. A BS may transmit an indication of dynamic UE parameter adaptation configuration to the UE to configure the UE with one or more dynamic UE parameter adaptation parameters. The indication of the dynamic UE parameter adaptation configuration may be included in a scheduling downlink control information (DCI) communication (e.g., a DCI communication that schedules uplink resources or downlink resources for the UE) and/or a non-scheduling DCI communication (e.g., a DCI communication that includes signaling information other than resource scheduling during data traffic inactivity for the UE).

The dynamic UE parameter adaptation configuration may be indicated by a value, a field, an M-bit (e.g., one or more bits) indicator that indexes into a table or another type of data structure that identifies a plurality of dynamic UE parameter adaptation configurations. Moreover, the table or other type of data structure may identify a unique or specific combination of dynamic UE parameter adaptation parameters for each of the plurality of dynamic UE parameter adaptation configurations.

In some cases, the BS may be made aware that the UE has received and applied a dynamic UE parameter adaptation configuration by receiving hybrid automatic repeat request (HARQ) feedback from the UE. For example, the UE may receive a scheduling DCI communication identifying the dynamic UE parameter adaptation configuration, may successfully decode the scheduling DCI communication, may identify and apply the dynamic UE parameter adaptation configuration in the scheduling DCI communication, and may transmit a HARQ acknowledgement (ACK) with the dynamic UE parameter adaptation configuration applied.

In some cases, the BS may be unaware or may lose track of the status of the dynamic UE parameter adaptation configuration configured at the UE. For example, the UE may not be configured to transmit HARQ feedback for non-scheduling DCI communications. Thus, if the BS transmits a dynamic UE parameter adaptation configuration to the UE in a non-scheduling DCI communication, the BS will not receive HARQ feedback and will not know if the UE successfully decoded the non-scheduling DCI and applied the dynamic UE parameter adaptation configuration.

As another example, even though the UE may transmit a HARQ ACK for a scheduling DCI, the BS may fail to receive the HARQ ACK (e.g., due to poor link quality). Thus, the BS may not know whether the UE received and applied the dynamic UE parameter adaptation configuration.

As another example, the BS may transmit a dynamic UE parameter adaptation configuration to the UE in a scheduling DCI communication, and the UE may successfully decode the scheduling DCI communication but may not successfully decode a physical downlink shared channel (PDSCH) communication scheduled by the scheduling DCI communication. In this case, the UE may transmit a HARQ negative ACK (NACK) to the BS. The BS may receive the NACK and may be unable to determine, based at least in part on the HARQ NACK, whether the UE failed to decode the PDSCH communication only or failed to decode both the PDSCH communication and the scheduling DCI communication. Thus, the BS may not know whether the UE received and applied the dynamic UE parameter adaptation configuration.

Some aspects described herein provide techniques and apparatuses for a dynamic UE parameter adaptation status report. A UE and a BS may synchronize the status of the dynamic UE parameter adaptation status of the UE using a dynamic UE parameter adaptation report, which may include a physical layer status report (e.g., a dynamic physical layer status report) or similar type of report. To obtain an indication of the dynamic UE parameter adaptation configuration configured at the UE at any particular time, the BS may transmit an indication to transmit the dynamic UE parameter adaptation report. The UE may receive the indication and may transmit dynamic UE parameter adaptation report, which may indicate the dynamic UE parameter adaptation configuration configured at the UE. In this way, the BS obtains the dynamic UE parameter adaptation configuration configured at the UE and is permitted to configure dynamic UE parameter adaptation updates for the UE. The dynamic UE parameter adaptation updates may be used to reduce power consumption by the UE, may be used for dynamic control of IoT devices, and may be used for dynamic control and latency reduction for ultra-reliable low-latency communication (URLLC), among other purposes.

FIGS. 3A and 3B are diagrams illustrating one or more examples 300 of a dynamic UE parameter adaptation status report, in accordance with various aspects of the present disclosure. As shown in FIGS. 3A- and 3B, example(s) 300 may include communication between a UE (e.g., UE 120) and a BS (e.g., BS 110). In some aspects, the UE and the BS may be included in a wireless network such as wireless network 100. The UE and the BS may communicate on an access link, which may include an uplink and a downlink.

In some aspects, the UE may be configured with one or more dynamic UE parameter adaptation parameters for power saving purposes. For example, the BS may transmit a dynamic UE parameter adaptation configuration to the UE to configure the UE with one or more dynamic UE parameter adaptation parameters. The BS may transmit an indication of the dynamic UE parameter adaptation in a scheduling DCI communication, in a non-scheduling DCI communication, and/or the like.

In some aspects, the one or more dynamic UE parameter adaptation parameters may include a bandwidth part (BWP) switching parameter, which may be a dynamic UE parameter adaptation parameter that may be used to configure the UE to switch between a BWP having a large bandwidth to another BWP having relatively smaller bandwidth such that the UE is to monitor fewer frequency resources, which reduces power consumption of the UE. In some aspects, the one or more dynamic UE parameter adaptation parameters may include a physical downlink control channel (PDCCH) monitoring parameter, which may be a dynamic UE parameter adaptation parameter that may be used to configure the UE with a PDCCH monitoring periodicity (e.g., in slots, in symbols, and/or the like) that permits the UE to less frequently monitor for PDCCH communications, which reduces power consumption of the UE.

In some aspects, the one or more dynamic UE parameter adaptation parameters may include a PDSCH monitoring parameter, which may be a dynamic UE parameter adaptation parameter that may be used to configure the UE with a PDSCH monitoring periodicity (e.g., in slots, in symbols, and/or the like) that permits the UE to less frequently monitor for PDSCH communications, which reduces power consumption of the UE. In some aspects, the one or more dynamic UE parameter adaptation parameters may include a cross-slot scheduling parameter, which may be a dynamic UE parameter adaptation parameter that permits the UE to be scheduled using cross-slot scheduling (e.g., where a scheduling DCI is permitted to schedule a downlink communication or uplink communication in a different slot than the slot in which the scheduling DCI is transmitted), which reduces power consumption of the UE.

In some aspects, the one or more dynamic UE parameter adaptation parameters may include a MIMO layers parameter, which may be a dynamic UE parameter adaptation parameter that configures the UE to switch between a quantity of active MIMO layers. The MIMO layers parameter may be used to deactivate MIMO layers for the UE such that the UE is permitted to deactivate various radio frequency (RF) chain components, which reduces power consumption of the UE. In some aspects, the one or more dynamic UE parameter adaptation parameters may include a secondary cell (SCell) dormancy parameter, which may be a dynamic UE parameter adaptation parameter that may be used to configure the UE to deactivate an SCell of the UE such that UE is to monitor fewer cells, which reduces power consumption of the UE.

As shown in FIG. 3A, and by reference number 302, the BS may transmit, to the UE, an indication to transmit a dynamic UE parameter adaptation report so that the dynamic UE parameter adaptation status of the UE may be synchronized between the BS and the UE. The dynamic UE parameter adaptation report may include a physical layer status report (e.g., a dynamic physical layer status report). In some aspects, the BS may transmit the indication based at least in part on transmitting, to the UE, a non-scheduling DCI communication that includes an indication of a dynamic UE parameter adaptation configuration. In some aspects, the BS may transmit the indication based at least in part on receiving, from the UE, a HARQ NACK associated with a scheduling DCI communication that includes an indication of a dynamic UE parameter adaptation configuration. In some aspects, the BS may transmit the indication based at least in part on not receiving HARQ feedback for a scheduling DCI. In some aspects, the BS may transmit the indication for other purposes and at other times.

In some aspects, the BS may transmit the indication in various types of downlink communications, such as a radio resource control (RRC) communication, a medium access control control element (MAC-CE) communication, a DCI communication, and/or the like. As an example, the BS may transmit an indication to periodically or semi-persistently transmit the dynamic UE parameter adaptation report in an RRC communication or MAC-CE communication. In this case, the RRC communication or MAC-CE communication may configure the UE to transmit the dynamic UE parameter adaptation report a plurality of times in a periodic or semi-persistent manner. In some aspects, the RRC communication or MAC-CE communication may further identify one or more physical uplink control channel (PUCCH) resources (e.g., time-domain resources, frequency-domain resources, and/or the like), one or more grant free physical uplink shared channel (PUSCH) resources, and/or the like in which to periodically or semi-persistently transmit the dynamic UE parameter adaptation report.

As another example, the BS may transmit a dynamic indication to transmit an aperiodic dynamic UE parameter adaptation report (e.g., a single dynamic UE parameter adaptation report that is triggered based at least in part on the dynamic indication being received at the UE) in a DCI communication. In some aspects, DCI communication may be a new DCI type specifically configured for requesting aperiodic dynamic UE parameter adaptation reports (e.g., a dynamic UE parameter adaptation DCI communication). In some aspects, the DCI communication may be a scheduling DCI communication or non-scheduling DCI communication repurposed for requesting aperiodic dynamic UE parameter adaptation reports. As an example, a resource allocation field in a non-scheduling DCI communication may be repurposed to include the indication to transmit the aperiodic dynamic UE parameter adaptation report (e.g., because the resource allocation field may be otherwise unused in the non-scheduling DCI communication as the non-scheduling DCI communication does not schedule resources for an associated downlink or uplink communication).

In some aspects, the DCI communication may further identify one or more PUCCH resources, one or more grant free PUSCH resources, or one or more dynamically granted PUSCH resources, and/or the like in which the aperiodic dynamic UE parameter adaptation report is to be transmitted.

In some aspects, the indication to transmit the dynamic UE parameter adaptation report may further indicate the information that is to be included in the dynamic UE parameter adaptation report. For example, the indication to transmit the dynamic UE parameter adaptation report may indicate that the dynamic UE parameter adaptation report is to include an indication of the dynamic UE parameter adaptation configuration configured at the UE (e.g., the dynamic UE parameter adaptation configuration configured at the UE at the time the indication to transmit the dynamic UE parameter adaptation report is received at the UE). As another example, the indication to transmit the dynamic UE parameter adaptation report may indicate that the dynamic UE parameter adaptation report is to include an indication of the dynamic UE parameter adaptation configuration most recently received from the BS.

As another example, the indication to transmit the dynamic UE parameter adaptation report may indicate that the dynamic UE parameter adaptation report is to include an explicit indication of one or more dynamic UE parameter adaptation parameters configured at the UE. In some cases, a dynamic UE parameter adaptation parameter, such as an SCell dormancy parameter, may be time limited in that the UE is to use the SCell dormancy parameter for a particular amount of time and then switch to another SCell dormancy parameter (e.g., a default SCell dormancy parameter). Thus, as another example, the indication to transmit the dynamic UE parameter adaptation report may indicate that the dynamic UE parameter adaptation report is to include an indication of a remaining amount of time that the UE is to use a timer-based dynamic UE parameter adaptation parameter.

As another example, the indication to transmit the dynamic UE parameter adaptation report may indicate that the dynamic UE parameter adaptation report is to include one or more other types of reports piggybacked on the dynamic UE parameter adaptation report, such as a power headroom report, a buffer status report, and/or the like.

As shown in FIG. 3B, and by reference number 304, the UE may receive the indication to transmit the dynamic UE parameter adaptation report and may transmit the dynamic UE parameter adaptation based at least in part on receiving the indication. For example, the UE may periodically or semi-persistently transmit the dynamic UE parameter adaptation report to the BS based at least in part on receiving an indication to periodically or semi-persistently transmit the dynamic UE parameter adaptation report. As another example, the UE may transmit an aperiodic dynamic UE parameter adaptation report to the BS based at least in part on receiving a dynamic indication to transmit the dynamic UE parameter adaptation report.

As another example, the UE may transmit the dynamic UE parameter adaptation in the resources (e.g., PDSCH resources, PUCCH resources, and/or the like) indicated along with the indication to transmit the dynamic UE parameter adaptation report. As another example, the UE may include, in the dynamic UE parameter adaptation report, the types of information indicated by the indication to transmit the dynamic UE parameter adaptation report, such as any of the information identified above.

In this way, the UE and the BS may synchronize the status of the dynamic UE parameter adaptation status of the UE using a dynamic UE parameter adaptation report. To obtain an indication of the dynamic UE parameter adaptation configuration configured at the UE at any particular time, the BS may transmit an indication to transmit the dynamic UE parameter adaptation report. The UE may receive the indication and may transmit dynamic UE parameter adaptation report, which may indicate the dynamic UE parameter adaptation configuration configured at the UE. In this way, the BS obtains the dynamic UE parameter adaptation configuration configured at the UE and is permitted to configure dynamic UE parameter adaptation updates for the UE.

As indicated above, FIGS. 3A and 3B are provided as one or more examples. Other examples may differ from what is described with respect to FIGS. 3A and 3B.

transmit, to a user equipment (UE), an indication to transmit a dynamic UE parameter adaptation report, wherein the dynamic UE parameter adaptation report is to include an indication of a dynamic UE parameter adaptation configuration most recently received from the network entity, wherein the dynamic UE parameter adaptation report indicates at least one or more dynamic UE parameter adaptation parameters configured at the UE, wherein the one or more dynamic UE parameter adaptation parameters comprise at least one of: a bandwidth part switching parameter, a physical downlink control channel monitoring parameter, a physical downlink shared channel monitoring parameter, a cross-slot scheduling parameter, a quantity of multiple input multiple output layers parameter, or a secondary cell dormancy parameter; and

receive, from the UE, the dynamic UE parameter adaptation report based at least in part on transmitting the indication.

23. The network entity of claim 22, wherein the indication to transmit the dynamic UE parameter adaptation report comprises:

wherein the one or more processors, when receiving the dynamic UE parameter adaptation report, are configured to:

periodically or semi-persistently receive the dynamic UE parameter adaptation report based at least in part the indication to periodically or semi-persistently transmit the dynamic UE parameter adaptation report.

24. The network entity of claim 23, wherein the one or more processors, when periodically or semi-persistently receiving the dynamic UE parameter adaptation report, are configured to:

periodically or semi-persistently receive the dynamic UE parameter adaptation report in at least one of:

one or more physical uplink control channel resources, or

one or more grant free physical uplink shared channel resources.

25. The network entity of claim 22, wherein the indication to transmit the dynamic UE parameter adaptation report comprises:

receive the aperiodic dynamic UE parameter adaptation report based at least in part on the dynamic indication.

26. The network entity of claim 25, wherein the dynamic indication comprises:

a scheduling DCI repurposed to carry the dynamic indication, or

a non-scheduling DCI that implicitly indicates the dynamic indication.

27. The network entity of claim 26, wherein the one or more processors, when receiving the aperiodic dynamic UE parameter adaptation report, are configured to:

receive the aperiodic dynamic UE parameter adaptation report in at least one of:

one or more physical uplink control channel resources (PUCCH),

one or more grant free physical uplink shared channel (PUSCH) resources, or

one or more dynamically granted scheduled PUSCH resources.
